Life Science: Biology: scope and sequence

Investigating the Chemistry of Life · Cells, Membranes & Exchange · Body Systems, Signals & Homeostasis · Matter & Energy in Living Systems · Cell Division, Reproduction & Development · DNA, Inheritance & Gene Expression · Evolution, Ancestry & Biodiversity · Ecosystems & Conservation Decisions

Across 36 weeks that is roughly 1.1 lessons and about 1.5 hours a week. A week-by-week calendar for the whole grade is at the Grade 10 year plan.
